CONVEYEB-FEEDING MECHANISM.

Specification of Letters Patent.

Original application filed August 26, 1910, Serial No. 579,110. Divided and this application filed February 5, 1914. Serial No. 816,725.

To all whom it may concern:

Be it known that I, ERASTUS E. VVINKLEY, a citizen of the United States, residing at Lynn, in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements in Conveyer- Feeding Mechanism; and I do hereby declare the following to be a. full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to mechanism for imparting an intermittent feed movement to a conveyer.

The object of the present invention is to provide a simplified mechanism adapted to either rectilinear or rotary movement 0 a conveyer, by which a step-by-step advance will be insured with a positive locking of the conveyer against backward movement during the pause between the feeding steps.

In accordance with this object an inoportant characteristic of the invention is found in the novel construction and arrangement of the feeding and locking devices whereby they are caused to cooperate 1n advancing the conveyer step -by-step and 1n locking it from movement during the period between the feeding steps.

To the accomplishment of this object and such others as may hereinafter appear, as will be readily understood by those skilled in the art, the invention comprises the features and combinations of parts hereinafter described and particularly pointed out in the appended claims.

In the accompanying drawings the essential principles of the invention are shown as'applied to the rotary conveyer table, utilized for transferring heels from the source of supply'to the cutting mechanism, of the heel shaping machine illustrated and described in my co-pending application Ser. No. 579,110, filed August 26, 1910, from which the present application has been divided.

In the accompanying drawings: Figure 1 is an end elevation of that portion of the frame of the heel shaping machine of my co-pending application which supports the novel conveyer feeding mechanism, together with said mechanism; Fig. 2 is a right side elevation of the parts shown in Fig. 1 with the frame broken away to better disclose the 5.5. mechanism; Fig. .3; isa plan of the. conveyer Patented Apr. 25, 19113.

feeding mechanism; Fig. 1 is an elevation of the parts shown in Fig. 3; and Fig. 5 is a transverse section on the line 5 5 of Fig. 4, looking in the direction of the arrows.

In the embodiment of the invention illustrated in the drawings the conveyer, for the present purposes, may be represented as a horizontal rotary table 1. The conveyer 1 is mounted on the upper end of a vertical shaft 2 suitably 'ournaled in the main frame F. The lower end of the shaft is seated in a journal 3 in the cross brace F and a sleeve 4 surrounds the shaft between the conveyer 1 and the journal 3.

An intermittent rotation of the shaft 2 and the conveyer 1 is produced by mechanism comprising a pinion 29 fixed on the lower end of the shaft, Fig. 1, which pinion is engaged alternately by a conveyer locking-rack 3 and a conveyer feeding or actuat- 75 ing rack 31, which are provided, as shown in Fig. 5, with cylindrical surfaces, so that they maybe swung into engagement with the pinion across its plane of movement about a horizontal axis lying substantially in the plane of the latter. The rack 30 forms an integral part of an elongated rocking frame comprising a bar 32 and endmembers 33 connecting the rack and the bar. These end members are loosely pivoted on arod 34: which is mounted at its ends in sleeves 35 and 36 carried at the ends of brackets F and F on the frame F of the machine. These sleeves confine the rocking frame against endwise motion but it is free to rock on the rod 34 so as to throw the conveyer locking-rack 30 into and out of engagement with the pinion 29. This rocking movement is produced by mechanism comprising a crank-arm 37 integral with the frame and pivoted by a universal joint 38, see Fig. 1, to the upper end of a rod 39, the lower end of which is pivoted by a univer' sal joint 10, see Fig. 2, to one arm 11 of a bell-crank lever loosely mounted on a shaft 12 journaled in the lower part of the frame F of the machine. The bell-crank lever has a second arm 43 carrying a cam-roll 44: which engages a cam 45 on the cam-shaft C, Figs. 1 and 2, journaled in the frame F above the shaft 12.

The conveyer actuating rack 31 is segmental in cross section and is provided with a hub 46 loosely mounted on the rod 31 and free to. rock thereon. Thishub is. also-free 11a to slide on the rod, as it is shorter than the rocking frame of which the conveyer locking-rack forms a member. The rock ing movements of the actuating-rack are produced by the rocking movements of the rocking frame, since the side faces of the actuatingrack are closely-embraced by locking-rack 30 at one side and the bar 32 at the other side, as shown in Fig. 5. cam mechanism, heretofore described, 09erates to rock the rame and thus throw the two racks 30 and 31 alternately into engagement with the pinion 29. actuating rack has been so engaged with the pinion, it is moved longitudinally rod 34 to rotate the pinion, and thus to rotate the shaft 2 and the conveyer 1. To this end the actuating rack is engaged by a segmental gear 47 carried upon arms 48 .pivotally mounted on the shaft 42, Figs. 1 and 2. One of these arms carries a cam-roll 49 which engages a cam 50 on the camshaft C. This cam acts to swing the segmental gear at the proper time to move the actuating-rack longitudinally and rotate the conveyer 1. After this movement has been completed the cam 45 operates on the crank arm 37 to rock the actuating-rack out of, and the locking-rack into, engagement with the pinion 29, so that the conveyer is firmly locked against accidental rotation between the feeding movements. While the parts are so locked, the actuating-rack is given a reverse longitudinal movement by its cam-mechanism, to bring it into position to again rotate the pinion in the same directio he cam-shaft C from which the mechanlsm heretofore described derives lts move- I, 52, which is loosely journaled on one end of the shaft 42. To this pulley is fixed a pinion 53 which meshes with a pinion 54, Fig, 1, fixed on one end of the camshaft C.

As will be readily apparent to those skilled in the artthe invention is not limited in its application to advancing a conveyer in an angular or circular path but may easily be adapted, by the skilled mechanic, to rectilinear movement. Furthermore, while, as hereinbefore stated, the accompanying drawings illustrate the essen tial principles of the invention, a skilled mechanic may readily make changes in the proportions and relative arrangement of the features and combinations of parts described to adapt the newly discovered mechanism toa particular use without departing from the scope of the invention which is defined in its true breadth in the appended claims.
